Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731928, here are decompositions:

61 + 8731867 = 8731928
67 + 8731861 = 8731928
97 + 8731831 = 8731928
109 + 8731819 = 8731928
151 + 8731777 = 8731928
229 + 8731699 = 8731928
241 + 8731687 = 8731928
349 + 8731579 = 8731928

Showing the first eight; more decompositions exist.
